RAILROAD CAR VENTILATOR Filed April 28, 1945 2 Sheets-Sheet 2 Inventor Patented Jan. 16, 1945 GAR VENTILATORI J' oseph l. Malloy, Washington, ma, 7 Application April 28, 1943, Se'r-ia-l: Not 484,889 2 Claims. (oi; 98-19) The present invention relates to new and use- 1 ful improvements in railroad car ventilators and has for its primary object to provide, ina manner as hereinafter set forth, a device of this character which is adapted to cause the withdrawal of smoke, odors, foul and warm air from the car while excluding cinders, rain, drafts, etc.

Another very important object of the invention is to provide a ventilator of the aforementioned character comprising a novel construction andarrangement whereby access to the interior of the device may be'expeditiously had for maintenance.

Other objects of the invention are to provide a ventilator of the character described which will be comparatively-simple in construction, strong, durable, highly eflicient and reliable in use,

compact, attractive in appearance and which may be manufactured and installed at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding parts throughout the several views, and wherein- Figure 1 is aview in side elevation, showing a ventilator constructed in accordance with the present invention installed on a railroad car.

Figure 2 is a vertical sectional view, taken substantially on the line 2-2 of Figure 1.

Figure 3 is an elevational view, looking at on the panel 4 of a railroad car 5 between the top and bottom decks 6 and I, respectively, of said car. The plate I is mounted on the panel 4 over a circular opening 8 in said panel.

I The plate I comprises an outwardly pressed central portion 9 having formed therein a cir- I3 pass through the marginal portions of the screen II.

The plateI further includes an inclined top I4 and apertured side flanges I5. Depending from the free or outer edge of thetop I4 is an integral lip I6. A depending flange I! is secured beneath the top I4 in spaced, opposed relation to the lip I6.

Removably mounted on the plate I is a hood I8 which, as best seen in Figure 2 of the drawings, is open'at its bottom. The hood I8 includes an inclined top I9 which terminates in an integral, upstanding flange 20 which is engaged beneath the top I4 between the lip I6 and the flange I I. The hood I8 further includes diagonal sideportions 2| having formed integrally therewith apertured flanges 22 which are engageable between the flanges I5 of the plate I. Bolts 23 detachably secure the apertured flanges I6 and 22together.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing, Briefly, as the car travels in either direction, smoke, odors and air therein will be drawn through the openings Band In and out through the open bottom of the hood I8 ina well known manner. The construction and arrangement is such as to exclue all dirt, cinders, rain, etc., from the car. By simply removing thev bolts 23, the hood may be detached to facilitate access to the screen II and the interior of the device. The portions 2| of the hood I8 comprise inturned flanges 24 on their upper ends which are secured at 25 to the top I9 of said hood.

It is believed that the many advantages of a railroad car ventilator constructed in accordance withthe present invention will be readily understood and although a preferred embodiment of the' device is as illustrated and described, it is to be understood that changes in the details of con- 40 struction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

Having described theinvention, what is claimed as new is:

1. A ventilator of the. character described com prising a metallic plate for mounting vertically cular opening I 0 in registry with the opening a 8. Mounted on the portion 9 of the plate I over the opening I0 is a screen I I. A ring I2 secures the screen II in position, said ring, in turn, be: ing secured to the plate I by bolts I3. The bolts on the panel of a railroad car between the top and bottom decks of said car, said plate including an outwardly pressed central portionhaving a circular opening therein for registry with an opening in the panel, a screen over the. firstnamed opening, a ring removably mounted on the plate for securing the screen in position thereon,

the plate further including an inclined top, an

integral lip depending from the top, a flange mounted beneath the top and depending therefrom in spaced, opposed relation to the lip, vertical side flanges on the plate, and a hood removably mounted on the plate, said hood being open at its bottom and including an inclined top, an integral flange rising from the second-named top and engageable beneath the first-named top between the lip and first-named flange, said hood further including diagonal side portions and flanges integral with said side portions, .the lastnamed flanges being engageable between the second-named flanges, and means for detachably securing said last-named flanges to said secondnamed flanges.

2. A ventilator of the character described com prising a plate for mounting vertically on the panel of a railroad car between the top and bottom decks of said car, said plate including an outwardly pressed central portion having a circular opening therein for registry with an open- .ing in the panel, a screen over the first-named plate, said plate further including an inclined top, an integral lip depending from the top, a flange mounted beneath the top and depending therefrom in spaced opposed relation to the lip, vertical side flanges on the plate, and a hood removably mounted on the plate, said hood including an inclined top, an integral flange rising from the second-named top and engageable beneath the first-named top between the lip and firstnamed flange, said hood further including diagonal side portions and flanges integral with said side portions, the last-named flanges being engageable between the second-named flanges, and means for detachably securing said last-named flanges to said second-named flanges.
